The Rosary has been a major influence in Roman Catholic thought for over 500 years while paving the way for a greater understanding of the mystery of Christ celebrated within family prayer.

The Rosary is the tradition-distilled essence of Christian devotion in which vocal and mental prayer unite the whole person in effective and purposeful meditation on the central mysteries of Christian belief. The Rosary thus joins the human race to God through Mary whom God chose from all time for the specific purposes of mother and intercessor.

The historical development of the Rosary begins with the desert fathers and their need to find a system to ease their laborious and repetitive prayer life. It is generally agreed by scholars that a system for counting repetitive prayers began with the Hindus some nine centuries before Christ. Prayer counters such as rocks, sticks or notches in wood were employed to ensure that the proper number of prayers were recited. Over time, counters and psalms were united into a "three groups of fifty" format (Na tri coicat) so that "fifties" could be used for personal and/or penitential prayer.

The fifteenth century provided the development period for the many facets of today's Rosary. During this period the Dominican influence with the Rosary grew and was fostered through both fact and legend. Although the Dominicans were not the sole originators of the Rosary, their influence in the growth, devotion and spread of this prayer cannot be denied. It would not be inaccurate to call them the principal promoters and defenders of the Rosary through history.

The fifteenth century saw the Rosary begin its development into the familiar prayer form we know today. The Our Father came intact from the Gospel of Matthew. The Hail Mary developed from the scriptural greetings of Gabriel and Elizabeth to Mary in Luke's Gospel, plus a popular exhortation in use by the laity of that period. The Glory Be was used as a common doxology from the earliest of Christian times when praying the psalms. The Salve Regina, a later addition to the Rosary, states all relevant medieval themes about the Blessed Virgin Mary. Its affiliation with the Rosary came about through popular practice although its precise origin within the devotion is not known. The Apostles' Creed along with the rosary pendant were also later developments, being added to the Rosary only in the early seventeenth century.
